Common sense is often never utilised into becoming common practice. This comes from the known fact that human beings are primarily emotional beings, therefore rarely taking logical action.
Despite knowing that a course of action will be best for someone, oftentimes other actions are taken as they originate from a place of emotional reasoning. Negative outcomes are often received as a result.
Taking a step back to reconsider what the best approach is from a reasoning stand point can be the difference between a positive or negative consequence.
